The F2000 is a great weapon to mod with. Alone the F2000 has a bad recoil if you try holding down the iron sights, or scopes. Although with a modded controller, automatic weapons shoot a bit slower, which causes some weapons to become horrible. But with the F2000, the weapon becomes even greater. With the mod, the F2000 shoots a bit slower, but with zero kick, which makes the weapon deadly accurate and powerful at the same time.

Simpler terms:

1. The F2000 has a bad recoil when aiming down the iron sights
2. With a mod the recoil is reduced
3. The gun becomes deadly accurate, along with the same damage
